The new wind power system HIL uses FPGA to realize real-time simulation of the motor and power electronic converter in the wind turbine; if the wind power system contains part of the AC grid such as infinity and transmission line, the CPU can be used for real-time simulation, simulation system and The actual controller being tested forms a closed loop through the actual signal connections. Using the HIL platform based on FPGA or FPGA-based co-simulation to simulate the wind power system, it is convenient to test the fan inverter controller in various working conditions, especially the grid fault condition; on the other hand, HIL The platform can easily reproduce various meteorological conditions encountered by the fan system at the site, truly reproduce the on-site working conditions, and can easily complete relevant scientific research, testing and debugging work in the laboratory environment.
The HIL wind power system test platform can accurately convey information, using precision resistors and shunts, which can feedback the current information in the circuit. At present, these supporting systems are further improved, and the integration of the structural smart grid can make the wind power system more intelligent and can control the wind power generation facilities at a remote location.
